BELTING.

Specification of Letters Patent.

Patented Dec. 30, 1919.

Application filed February 6, 1919. Serial No. 275,326.

To all whom it may concern:

Be it known that 1, JAMES BARTON, a citizen of the United States, residing at Newark, county of Essex, and State of New Jersey, have invented certain new and useful Improvements in Belting, of which the following is a full, clear, and exact description.

The invention which constitutes the subject matter of this application relates to a woven belting the body of which is composed largely, if not entirely, of hair material and the edges of which are composed of cotton material only. i

The drawing herein illustrates a perspective view of the invention the reference letters A desi nating the edges of cotton material and E the body portion of the belting.

The woven belting above referred to is manufactured substantially as follows: The warp threads, composing what is termed the body of the belt, may be all hair yarn or may be hair and cotton yarn mixed. In order therefore to make a belt with cotton edges the hair yarn on the beam near the edges is replaced by cotton yarn. The weft threads are of course all cotton; therefore the provision of warp threads of cotton on either edge of the beam will result in a woven article both edges of which are made entirely of cotton.

It has been found that by having the edges of the woven belt made of cotton a more uniform edge is obtained, as the tension which can be secured from the weft threads by means of the shuttle is greater when pulling against cotton than when pulling against hair threads. This uniformity of the edges makes the belt truer and prevents curving.

With the edges made of cotton the belt will withstand more abrasive action as in rubbing against stationary objects such as shifters. The cotton edges also aid in preventing the belt from cracking across its face as it has greater resistance than an edge of hair; that is to say, when a belt cracks it commences at its extreme edges.

Another very important advantage of this form of belting is the fact that the cotton edges are capable of being treated with chemicals, such as a mixture of oils and asphalt material, which serve to protect the same from the abrasive action caused by rubbing against stationary objects. This property is due to the fact that cotton absorbs and retains these materials to a greater extent than a hair belt or a belt of hair and cotton.

It will therefore be apparent from the above that I have devised a belt which has numerous advantages over the kinds of belting heretofore in vogue.

What I claim is:

l. A belting the body portion of which comprises hair material and the edges of which are made entirely of cotton material.

2. A belting the body portion of which consists of warp threads of hair and cotton material, and the weft threads of which entirely are of cotton, in combination with edges which are entirely of cotton.

3. A hair belting the edges of which are made entirely of cotton material.

In testimony whereof I have hereunto affixed my signature.

JAMES BARTON.
